I cleaned my computer the other day and before the cleaning everything was fine. Im not sure if I knocked something loose but everyone once in a while I will lose signal to the monitor and have to hard boot. I boot back up and everything seems to be ok. Could I maybe have tapped the video card and made it come out of the socket a little? I have a 2.4GHz processor, I run a 6800GT video card. My computer has a lot of space inside so I dont feel its overheating. I can connect online and stuff fine its just my monitor light turns orange from green and I lose picture. My monitor is a View Sonic UltraBrite A90f+. Any input or thoughts would be appreciated...thanks
